摘要
本文提出了位于半无限弹性体地基上带有曲线边界的MIND LIN板的有限元——链杆法解.用有限单元法计算板的位移,用高斯积分法求地基沉降,用链杆法求板与地基之间的接触反力.该法的提出,增大了地基板问题的求解范围而计算效率明显提高.
A new method to analyze the Mindlin plates with curved boundaries on elastic half-space subgrade is presented in this paper.The finite element method is used to find the displacements of plates, the Gauss integral method to get subgrade settlements and the rigid bar method to determine the contact pressure between plates and subgrade.By virtue of the advantages of FEM and RBM, the computational efficiency is remarkably improved.
